===Meaning===
A [[particle]] is a small piece of [[matter]].
===About Particles===
: [[Particle]]s are often made of other, smaller, [[particle]]s.
: [[Particle]]s are usually shown as round in shape but may be made of smaller [[particle]]s making their shape a combination of the shapes of other [[particle]]s stuck together.

===Meaning===
'''Particle''' is a general term used to describe a 'small' unit of [[matter]].
===About Particles===
: The term '''particle''' may be used to describe [[object]]s as large as several billion [[atom]]s (as in a [[soot]] [[particle]]) or as small as a smallest possible unit of [[matter]] known as a [[Fundamental Particle|fundamental particle]].
: In [[physics]] the term '''particle''' is used:
:*On larger scales to simplify calculations of the motions of [[object]]s by approximating them to be round with an even distribution of [[mass]]
:*On large groups of [[object]]s at smaller scales for calculations of bulk properties by approximating them to be [[Point Particle|point]]s with negligible [[Volume (Space)|volume]].
:*On [[atom]]ic and [[subatomic Particle|subatomic]] scales to name units of [[matter]] which are often repeated in nature (eg. the [[proton]] is a repeating unit of [[matter]] found in all [[atom]]s).
